They typically range from 26 inches to 29 inches long and can weigh between 13 ounces and 18 ounces.

Senior league baseball bat sizes range from 31 inches to 33 inches in length and are roughly 19 ounces to 25 ounces in weight, although some can go up to 30 ounces.

A player’s swing and power are partially determined by bat size, so getting a good fit for body type and skill level is essential. For younger players who are just learning their swing mechanics, choosing the correct bat length is especially important. The general rule for youth bats is that they should be no longer than shoulder height when standing upright with arms at sides. Proper bat size helps ensure balance and control while swinging.

Baseball Bat Size FAQs

What size baseball bat do I need?

There are multiple ways to determine the right bat size. A common, accurate, and easy way is by holding your arm out to the side, parallel to the floor. Then hold the knob (end) of the bat at the center of your chest, reaching it out along your arm. If the bat stretches to the end of your fingers, it’s a good size.

How do you pick the proper weight for a bat?

A good rule of thumb about bat weight is the older the player, the less weight drop you want. Keep in mind that the less weight drop, the heavier a bat will be. For example, a -10 bat will be lighter than a -5 bat.  

Does a heavier bat mean more powerful hits?

In theory, a heavier bat can mean more power. That said, the player swinging the bat must be able to maintain their bat swing speed to get distance and velocity from a hit.
